Hold'em table

Q8o on the button in a 3-handed game is a standard open; raising to 2.5bb puts pressure on the blinds and takes initiative with position.

96 suited is weak facing a raise and I'd be out of position in a multiway pot; folding preserves chips for better spots.

72s is too weak to defend out of position against a button open; folding avoids a dominated, low-equity spot.

J6o from the button is weak preflop; folding avoids committing chips with a marginal hand.

Button folded, so I am heads-up versus the big blind's random range. 72s has enough equity to complete for 50 into 150 rather than fold, and raising this weak suited hand is unnecessary.

Button folded, SB limped; 9c6c suited has decent playability and I have position postflop. Raising attacks the limper's capped range and takes the pot down often, with a playable hand if called.

72s is too weak to continue out of position after the big blind raises my limp; folding saves chips.

K8o is playable enough to open from the button in three-handed no-rake hold'em, so I raise to 2.5bb rather than flat or fold.

J5 offsuit in the small blind facing a 2.5x button open is a clear fold; it plays poorly out of position and is dominated by most opening ranges.

J6 offsuit is weak; facing a raise with only one opponent folded, not worth continuing from the big blind.

K5o on the button in a 3-handed game is a standard open; raising to 2.5bb takes the initiative and often wins the blinds outright.

5-7 offsuit facing a raise from the button with a BB still to act is a clear fold; not worth defending this weak holding.

J8 offsuit is too weak to defend out of position against a button open; folding avoids a dominated, poorly playable spot.

A5 suited is a strong button hand; raising to build the pot and take initiative against two limpers.

J7 offsuit is too weak to continue out of position against a button open; folding saves chips.

75 offsuit is a weak hand out of position against a button open; calling 150 to see a flop with a hand that rarely makes strong holdings is -EV, so fold.

54o is too weak to open even on the button in a three-handed pot; folding avoids paying a blind with a dominated offsuit hand.

Button folded, so it's blind vs blind; K7o is a standard open-raise from the small blind heads-up against the big blind, taking initiative with a 3x raise.

9h4h offsuit-ish weak hand facing a 3bb raise with only one other player; not worth calling out of position.
